Support for legacy systems that have included the UltraSPARC I, II, IIe, III, IIIi, III+, IV and IV+ processor architectures (as reported by the Solaris ‘psrinfo -pv’ command) has been removed. All Oracle SPARC Enterprise M-Series Servers and Oracle SPARC T-Series Servers will continue to be supported.

Note: Oracle Solaris 10 will continue to be a supported operating system for these affected platforms as per the current Oracle lifetime support policy.

The cacheFS cache filesystem designed to speed up network file system file access for networked computers has been removed. Improvements to NFS have meant that there is less of a need for a cache filesystem.

The /etc/hostname.<interface> files are no longer supported interfaces for storing persistent network configurations. Use the ipadm(1m) and dladm(1m) commands to configure the IP interfaces persistently.
